Sadiq Khan has signalled that his mayoralty remains committed to the Bakerloo Line extension through New Cross and Lewisham. In TfL's recently-published annual report, the project gets its own double page spread, which says:Work has started on building a case to extend
the Bakerloo line into southeast London.
If the Government gives the project the
green light, we expect to begin construction
in 2024. In 2015, we assessed possible routes. This
meant taking into account how each option
could improve connectivity and housing,
the engineering feasibility (for example,
tunnelling, which is complex and expensive,
must be kept to a minimum), how swiftly the
project can be completed, and the likelihood
that it could be paid for. Our assessment showed that a route
from Elephant and Castle to Lewisham,
via Old Kent Road, would offer significant
development opportunities, including up to
30,000 new homes. This could, in turn, help
with the costs of building the extension, by
securing contributions from new residential
and commercial developments along the line. Ending the route at Lewisham means we
can build the extension quickly and cost
effectively, hopefully completing the
project by 2030. And this doesn’t rule
out extending the line even further in
the future.

The Bakerloo extension was one of Khan's election commitments and this is simply more fine words, rather than action, but thanks to Monkeyboy for sharing this red meat nonetheless.
